1. How does oxygen get in and out? Oxygen gets in and out of the pigs body by the alveoli in the bronchioles. The bronchioles are in the two tubes that come from the trachea called the bronchial tubes. The alveoli look like a grape-like cluster of air sacs. Carbon dioxide and oxygen are exchanged with the capillaries.
2. How is oxygen and other materials moved throughout the body? Oxygen and other materials are then transported from the alveoli into the capillaries. The capillaries then go into the blood stream and the blood stream take the materials throughout the body.
3. Draw a diagram of the movement of oxygen and other materials through this system.
Question I Have:
What are the alveoli and capillaries made up of?
Answer to that Question:
Alveoli are made up of simple squamous epithelium; single layer of flattened cells with disc-shaped central nuclei and sparse cytoplasm; the simplest of the epithelium.
Capillaries are made of simple squamous epithelium also.
1. How does oxygen get in and out? Oxygen gets in and out of the crayfish's body through the gills.
2. How is oxygen and other materials moved throughout the body? To make the process more efficient, blood and water flow in opposite directions in structures like gills.
3. Draw a diagram of the movement of oxygen and other materials through this system.
Starfish:
1. How does oxygen get in and out? Starfish breathe through their feet. They also have little breathing tubes all over their bodies. It uses some of the bumps or spines on its surface to take in oxygen. It has a gill structure to take in the oxygen and release the carbon dioxide.
2. How is oxygen and other materials moved throughout the body? Oxygen and other materials are distributed through the body mainly by the fluid in the main body cavity; the hemal system may also play a minor role.
